Cardiovascular disease is the number one killer worldwide. Heart attacks occur when clogged coronary arteries prevent the flow of oxygen-rich blood to the heart. That causes heart muscle cells to die off, causing permanent damage. Stress, smoking, high blood pressure and lack of exercise are all factors that can lead to a heart attack. But scientists in Lübeck have also discovered some genetic components. In numerous studies, they have identified genes or gene defects that increase the risk of heart attacks. Their work may lead to the development of therapies to treat the affected people in time.

Mark Post from the Netherlands is convinced that one day soon, steaks will be grown in the laboratory. A professor of biomedicine at the University of Maastricht, he's an expert in tissue culturing. Some time ago, he had the idea that artificial beef and pork could be grown in the lab in much the same way that stem cells are used to grow artificial heart valves or artificial skin. He's already had his first success. In 2013, he presented the world's first lab-grown hamburger. It cost an astonishing ?250,000 to grow, but the price has already dropped significantly. Post is convinced that one day soon, lab-grown meat will play an important role in feeding the world. Because cattle farming is expensive and a burden on the environment, artificial meat could help solve many different problems. DW reporter Andreas Neuhaus presents the scientist and his research.

Brady, dean of the Goldman School of Public Policy at UC Berkeley.

Tune in for a rare opportunity to meet German astronaut and geophysicist, Alexander Gerst. In May 2014, Gerst flew to the International Space Station in a Soyuz spacecraft and returned six months later, having conducted a raft of scientific experiments for his "Blue Dot Mission." He wowed the world with images of Earth, taken from the ISS and shared on social media. And he became an inspiration for a generation of young European scientists. But why did Gerst want to go - as a scientist and as a human - and how does he see the future?
